Late-onset dysphagia lusoria

Symptomatic vascular rings are uncommon in adults. We report a case of dysphagia in a 48-year-old woman from a right-sided aortic arch with aberrant left subclavian artery and left-sided ligamentum arteriosum. Through a left posterolateral thoracotomy, the ligamentum was divided, relieving the patient’s dysphagia. Twenty-three cases of adult-onset dysphagia lusoria attributable to this anatomy have been reported. We recommend a left thoracotomy with division of the ligamentum as treatment.
